Suppose the force exerted by the air on one face of a cube is 8820N. Each side of the cube measures 30cm. Calculate the pressure on this face?
Divide 8820 N by the cube side area, 0.09 m^2.
The answer will be the pressure in Pascals
98000
suppose the force exerted by the air on one face of a cube is 8820 N.each side of the cube measure 30 cm. calculate the pressure on this face.?
To calculate the pressure on a face of the cube, we need to divide the force exerted by the air on the face by the area of that face. The formula for pressure is:
Pressure = Force / Area
First, let's convert the side length of the cube from centimeters to meters, as pressure is commonly measured in pascals (Pa) where 1 Pa = 1 N/m².
Given:
Force = 8820 N
Side length of the cube (s) = 30 cm = 0.3 m
To find the area of a face of the cube, we can use the formula:
Area = side length × side length
Area = 0.3 m × 0.3 m = 0.09 m²
Now, we can calculate the pressure:
Pressure = Force / Area
Pressure = 8820 N / 0.09 m²
Pressure ≈ 98,000 Pa
Therefore, the pressure exerted on the face of the cube is approximately 98,000 pascals.
